Abstract

In accordance with one aspect of the present disclosure, an electronic device includes a housing, a contact member attached to the housing, and a vibration generating device. The vibration generating device is fixed to the contact member or the housing. A gap is formed between a surface of the vibration generating device facing the housing and a surface of the housing facing the vibration generating device.

First claim

What is claimed is:

1. An electronic device comprising:
a housing;
a contact member attached to the housing;
an attaching part inside the housing; and
a vibration generating device, wherein
the vibration generating device includes:
a base including a protruding part formed with a first magnetic body and a recessed part,
the protruding part being attached to the recessed part,
a coil annularly wound around the protruding part;
a plate formed with a second magnetic body and facing the base,
an elastic member is coupled to the plate and the contact member directly or through another member,
the plate and the base form a magnetic circuit,
a magnetic gap is formed between the protruding part and the plate,
a flange part is provided at the base, and
the flange part is attached to the attaching part.

2. The electronic device according to claim 1 , wherein the plate has a first surface facing the base, and
a weight is arranged at a second surface of the plate on an opposite side of the base.

3. The electronic device according to claim 1 , comprising an elastic member supporting the plate with respect to the base.

4. The electronic device according to claim 1 , wherein a gap is formed between a surface of the base facing the housing and a surface of the housing facing the base.

5. An electronic device comprising:
a housing;
a contact member attached to the housing;
an attaching part inside the housing; and
a base including a protruding part formed with a first magnetic body and a recessed part,
the protruding part being attached to the recessed part,
a coil annularly wound around the protruding part;
a plate formed with a second magnetic body and facing the base,
an elastic member is coupled to the plate and the contact member directly or through another member,
the plate and the base form a magnetic circuit,
a magnetic gap is formed between the protruding part and the plate,
a flange part is provided at the base, and
the flange part is attached to the attaching part.

6. The electronic device according to claim 5 , wherein the plate has a first surface facing the base, and
a weight is arranged at a second surface of the plate on an opposite side of the base.

7. The electronic device according to claim 5 , comprising an elastic member supporting the plate with respect to the base.

8. The electronic device according to claim 5 , wherein a gap is formed between a surface of the base facing the housing and a surface of the housing facing the base.
